November 2 General Meeting "2012 - The Next Great End of the World?" by Chuck Pullen - instructor at Sierra College
Hype has been building for several years over the end of the Mayan Calendar on December 23, 2012, the Winter
Solstice. Some are making it into a prophecy of the end of days. Others are tying a host of conspiracies into the
"Mayan Apocalypse " including UFOs, shadow governments, and the Illuminati. Chuck informed us about the real
Mayan Calendar, past predictions of doom, and the business of selling the end of the world.

different scenarios for the origin of the Moon that address the answers to these questions.

March 2 "The Stormy Sun" by John Combes
The Sun appears to be a very stable star and compared with many other stars that would be the case. However,
considering the fragile nature of life on Earth, the Sun can pose some interesting and sometimes disastrous effects to
the well being of human and animal life. John explored some of the events caused by the Sun which have affected the
way we live.

February 2 "Dark Skies" by Jack Sales "Dark Skies 2"
Jack is the founder of the International Dark-Sky (IDA) Association. The goal of the IDA is to make people to be
aware of the importance of the loss of our dark skies. The preservation of dark skies is an important environmental
concern to astronomers, of course, but also for other aspects of our biosphere. Light pollution has been shown to
adversely affect circadian rhythms of sleep patterns and hormonal cycles of many living things, including us humans.
There is also an environmental concurrent effect due to wasting of energy for overused urban lighting. Jack discussed
these detrimental effects of "light pollution," and alternatives to reduce these effects.
